Gdansk Science Museum (Museum of Gdansk branch)

What to expect

The Gdansk Science Museum is a museum you climb: this branch of the Museum of Gdansk occupies the tower of St Catherine’s Church on Wielkie Młyny. Inside the tower you see the mechanisms of tower clocks, in its upper part a 50-bell carillon, and from the viewing terrace a panorama of the Main Town.

Now: closed (the branch opens seasonally from April to September). Google Maps shows the branch as temporarily closed, and in a Facebook post of 25 September 2026 the branch said it would see visitors again only in the spring. The museum does not currently give the season’s opening hours on its pages: the hours table on the branch page has no seasonal hours at the moment, so check the branch page or call before you go.

The museum calls itself the only museum of tower clocks in Poland, and the regional portal pomorskie.travel says the same and adds the history of timekeeping. Guide Marek Formela (zwiedzanietrojmiasta.pl) describes a collection spanning the whole era of mechanical and mechanical-electrical clockmaking and notes that every mechanism works, which you can tell from the loud ticking.

The viewing terrace is open whenever the museum is, and your admission ticket covers it. So you do not pay separately for the panorama of the Main Town.

Who it suits: people who like mechanisms and views from on high and do not mind stairs. As the museum puts it: “Get ready for stairs! Hundreds of steps await you!”. Families can buy a family ticket, and a blog about travelling with children described a visit in 2023, warning of very winding and steep stairs.

Who should skip it: wheelchair users and anyone who finds steep stairs hard. According to the accessibility statement, the entrance alone is a narrow staircase with 66 spiral steps, there is no lift, and the branch is not accessible to wheelchairs because it sits in a church tower. The branch has no toilet either.

How long: the museum says a visit takes at least 30 minutes. It is a short visit that pairs easily with the Museum of Amber in the Great Mill, about 50 m away in a straight line.

Tips

• Season only. The branch opens only in season (details in the practical box). The general free-admission day that the Museum of Gdansk announces for its branches does not, according to its website, cover the seasonal branches, this one included, so do not count on it here.
• The ticket desk closes early. You can buy tickets up to 45 minutes before closing, and last entry falls at the same point. With a climb ahead, do not leave the visit to the last minute.
• Reduced and family tickets. Prices: standard ticket 26 PLN (about 6 EUR), reduced 19 PLN (about 4 EUR). Reduced tickets are for pupils, students and old-age and disability pensioners with a valid ID; the family ticket covers up to 8 people, one or two adults with children up to 18, and the group ticket starts at 10 people.
• Traffic lights on the stairs. A family blog described in 2023 the traffic lights at the entrance: you go up and come down the same winding stairs, so expect a short wait.
• Headphones for the ticking. At the ticket desk you can borrow magnifiers and noise-reducing headphones, and you will also be given disposable earplugs. They help a child sensitive to noise, because the working mechanisms tick loudly.
• Toilet before you go in. The branch has no toilet, so plan a break beforehand, especially with children.
• Carillon in winter too. The museum announces carillon concerts from the tower of St Catherine’s Church all year round, outside the branch’s season as well; the branch page gives their day and time.

Getting there

• Address: Wielkie Młyny 10, 80-849 Gdańsk, in the tower of St Catherine’s Church.
• Bus: according to the ZTM Gdańsk timetable, the nearest stops are “Katarzynki 01” (about 234 m) and “Heweliusza 01” (about 255 m); line 100 serves both.
• Tram: the stops “Dworzec Główny 01” and “Dworzec Główny 02” (about 316 and 318 m) are served by trams 2, 3, 6, 7, 8, 9, 10 and 12. Many bus lines also leave from the group of stops at the main railway station (Dworzec Główny), about 290-340 m from the tower.
• By car: the accessibility statement points to a guarded car park at ul. Katarzynki 4, about 160 m from the branch, with roughly 90 spaces.

Nearby

The tower pairs easily with museums within a few hundred metres (straight-line distances):

• Museum of Amber, Wielkie Młyny 16 - about 50 m. It is housed in the Great Mill (Wielki Młyn), which according to the museum the Teutonic Knights built around 1350, and it has its own opening hours outside the tower’s season too, so it is a good plan for winter.
• Museum of the Polish Post Office, plac Obrońców Poczty Polskiej 1/2 - about 430 m. Since 2003 it too has been a branch of the Museum of Gdansk; according to trojmiasto.pl it reopened on 5 October 2026 after 15 months of work, with an exhibition twice the size of the previous one.
• Gallery of Old Toys, ul. Piwna 19/21 - about 510 m. A private museum of Bernadeta and Wojciech Szymański, which according to trojmiasto.pl appeals to adults and children alike; it is the choice for families with children who want to see something more after the clock tower.

Background

The loud ticking in the tower of St Catherine’s Church has a longer history than the branch’s current name. Polish Wikipedia says the museum was founded in 1996 as a branch of what was then the Historical Museum of the City of Gdansk and until 2016 was called the Museum of Tower Clocks (Muzeum Zegarów Wieżowych). Today, as the Gdansk Science Museum, it belongs to the Museum of Gdansk.

On its website the museum recalls the former name and stresses that it is still the only museum of tower clocks in Poland. The same page points out that a 50-bell carillon hangs in the upper parts of the tower. Wikipedia and the museum agree on the former name, so the 2016 change concerned the sign, not the subject: tower clocks have remained the core of the exhibition.
